Vehicle Mobility Performance in Muskeg A Second Report
J. G. THOMSON
Development of the Canadian North, a subject of growing national interest, must in part await the development of better forms of transport. The estimated 500,000 square miles of muskeg terrain in the north combined with the" scarcity of roads make essential the early development of special purpose muskeg vehicles. Good progress has been made in the last eleven years in classifying muskeg and some progress has been made in determining its mechanical properties. Limited travel is now possible through the use of special purpose tracked vehicles which have been built without adequate design data. A program to provide data which can be used to optimise muskeg vehicle designs began in 1957. The res ults of the second phase of this program are presented in this report. It is shown that vehicle performance in muskeg is directly related to the mechanical properties of the muskeg. Further, it is shown that good design practice for tracked vehicles expected to operate in snow, sand, soft clays and loams is also good practice for muskeg vehicles. All indications a re that muskeg mechanics is properly a part of conventional soil mechanics. It may therefore be said that an extensive literature is now available to the muskeg vehicle designer. The literature of the science of soil mechanics and of the art of vehicle designer both applicable.
